Doctors of Narayana health city said the initial investigation was done, with the pattern of Kejriwal’s bouts of coughing and extensive imaging.

“He coughed because his enlarged soft palate and uvula (fleshy hanging extension at the back of the soft palate) and a slightly larger tongue caused kinematic problems and made it difficult for his tongue to move freely in the restricted space,” said the doctor. Source

In a laymen language , Kejriwal had a bigger tongue then it was required, which is been corrected through surgery.

Because of this surgery , Arvind Kejriwal would not be able to speak for some day’s. It is to note that Kejriwal is A diabetic.

Kejriwal, 48, is likely to be in the hospital for about a week under medical observation.
